.htaccess redirect for a form

Hey dear people,

I cannot get an https redirect to work for a user form I set up.

I want to be able to redirect from:

Here’s my htaccess, rule is in the last line:

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /
RewriteRule ^content/(.*)\.(txt|md|mdown)$ index.php [L]
RewriteRule ^site/(.*) index.php [L]
RewriteRule ^kirby/(.*) index.php [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^panel/(.*) panel/index.php [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*) index.php [L]

RewriteCond %{HTTPS} !=on
RewriteRule ^/?panel/(.*) https://%{SERVER_NAME}/panel/$1 [R]
RewriteRule ^/?application-form https://%{SERVER_NAME}/application-form [R,L]

At some point it worked for Safari and Chrome but not in Firefox, but I have no idea why and changed the file since then.
The website is located in a subfolder, which is why I set
RewriteBase /
The application-form is obviously just a subfolder of /content.

Thanks in advance for help,

May I. asked why you only redirect that page and the panel and not force HTTPS on the site?

Okay, well. Fair point. Is there any downside to doing that?

Thanks for the Edit.

No, to the contrary, where is the point of limiting HTTPS to individual pages? You are more likely to run into issues if you do what you were trying to. do.
